Mishash Formation
late Cretaceous geologic formation in Israel
The Mishash Formation is a Late Cretaceous (Campanian-Maastrichtian) geologic formation in Israel. The formation is correlated with the Duwi Formation of Egypt and the Amman and Ruseifa Formations of Jordan. Mosasaur fossils assigned to Prognathodon currii and pterosaur fossils have been recovered from the formation.
Stratigraphy
The lower boundary of the Mishash Formation lies atop the top of the underlying Menuha Formation, while the upper boundary is covered by the overlying Ghareb Formation. The Mishash Formation is divided into two members known as the Chert Member and Phosphate Member, with the latter overlying the former. Massive chert beds comprise the Chert Member, while the Phosphate Member is made up of cherts, phosphorites, porcellanites and organic-rich carbonates. The Phosphate Member is further divided into three units; the Phosphatic Carbonate Unit lies at the bottom of the member, followed by the Porcelanite Unit in the middle, and finally the Phosphorite Unit at the top.

Begin with the source’s own compact description: “Mishash Formation” is late Cretaceous geologic formation in Israel. The dossier treats that line as a proposition to test through Mishash, Formation and late, not as a finished interpretation.
Why this record matters
The phrase “late Cretaceous geologic formation in Israel” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Apr 15, 2026. The linked authority identifier is Q17113860. Authority coordinates are 30.200, 35.000. None of the 1 selected statements returned an explicit reference. The first chronological checks are 2008.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
